N8 Here is all you need to know. At the upper end grocery stores they sell coconut oil. It is what popcorn was popped in at the theaters years ago. It is a hard white solid at room temp and it will not caramelize like olive oil when heated. Put about 80% of the coconut oil you need for popping in the pan and the other 20% make up with bacon drippings. It won't taste like bacon and the coconut oil is very taste neutral. Pop and drizzle melted real butter and sprinkle salt on it and the party is over.
